2019-05-17i2c: mxc_i2c: Fix read and read->write xfers in DM modeTrent Piepho
This is an old driver that supports both device mapped and non-mapped mode, and covers a wide range of hardware. It's hard to change without risking breaking something. I have to tried to be exceedingly detailed in this patch, so please excuse the length of the commit essay that follows. In device mapped mode the I2C xfer function does not handle plain read, and some other, transfers correctly. What it can't handle are transactions that: Start with a read, or, Have a write followed by a read, or, Have more than one read in a row. The common I2C/SMBUS read register and write register transactions always start with a write, followed by a write or a read, and then end. These work, so the bug is not apparent for most I2C slaves that only use these common xfer forms. The existing xfer loop initializes by sending the chip address in write mode after it deals with bus arbitration and master setup. When processing each message, if the next message will be a read, it sends a repeated start followed by the chip address in read mode after the current message. Obviously, this does not work if the first message is a read, as the chip is always addressed in write mode initially by i2c_init_transfer(). A write following a read does not work because the repeated start is only sent when the next message is a read. There is no logic to send it when the current message is a read and next is write. It should be sent every time the bus changes direction. The ability to use a plain read was added to this driver in commit 2feec4eafd40 ("imx: mxc_i2c: tweak the i2c transfer method"), but this applied only the non-DM code path. This patch fixes the DM code path. The xfer function will call i2c_init_transfer() with an alen of -1 to avoid sending the chip address. The same way the non-DM code achieves this. The xfer function's message loop will send the address and mode before each message if the bus changes direction, and on the first message. When reading data, the master hardware is one byte ahead of what we receive. I.e., reading a byte from the data register returns a byte *already received* by the master, and causes the master to start the RX of the *next* byte. Therefor, before we read the final byte of a message, we must tell the master what to do next. I add a "last" flag to i2c_read_data() to tell it if the message is to be followed by a stop or a repeated start. When last == true it acts exactly as before. The non-DM code can only create an xfer where the read, if any, is the final message of the xfer. And so the only callsite of i2c_read_data() in the non-DM code has the "last" parameter as true. Therefore, this change has no effect on the non-DM code. As all other changes are in the DM xfer function, which is not even compiled in non-DM code, I am confident that this patch has no effect on boards not using I2C_DM. This greatly reduces the range of hardware that could be affected. For DM boards, I have verified every transaction the "i2c" command can create on a scope and they are all exactly as they are supposed to be. I also tested write->read->write, which isn't possible with the i2c command, and it works as well. I didn't fix multiple reads in a row, as it's a lot more invasive and obviously no one has every wanted them since they've never worked. It didn't seem like the extra complexity was justified to support something no one uses.

It is not very clear how these work in relation to the exact I2C xfers they produce. In paticular, the address length is somewhat overloaded in the read method. Clearly document the existing behavior. Maybe this will help the next person who needs to work on this driver and not break non-DM boards.

2019-04-11DM: I2C: Introduce 'u-boot, i2c-transaction-bytes' propertyLukasz Majewski
The 'u-boot,i2c-transaction-bytes' device tree property provides information regarding number of bytes transferred by a device in a single transaction. This change is necessary to avoid hanging devices after soft reset. One notable example is communication with MC34708 device: 1. Reset when communicating with MC34708 via I2C. 2. The u-boot (after reboot -f) tries to setup the I2C and then calls force_idle_bus. In the same time MC34708 still has some data to be sent (as it transfers data in 24 bits chunks). 3. The force_idle_bus() is not able to make the bus idle as 8 SCL clocks may be not enough to have the full transmission. 4. We end up with I2C inconsistency with MC34708. This PMIC device requires 24+ SCL cycles to make finish any pending I2C transmission. Signed-off-by: Lukasz Majewski <[email protected]>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <[email protected]>
